A 29 error code indicates a neutralizer drainage failure. The neutralizer is designed to drain condensate away from the heater. If the neutralizer and/or drain becomes blocked up, the unit will flash the 29 error code to prevent the burner from being flooded.
Common issues related to the 29 error code include:
1) Blockage in the condensate drain line
2) Incorrect condensate line piping (e.g. upward sloping of drain line, trapped drain line, incorrect size piping)
